To all whom it may concern;

Bo it known that I, JOSEPH OLDFIELD, manufacturers agent,'of the city of Toronto,

vin the county of York, in the'Provincey of l specification.

My invention relates to improvements in duplicating check books, and the object of the invention is, first, to provide ameans whereby the number that Ais printed backwardly on the duplicate sheet may be readily deciphered through the -sheet,and, secondly, to provide a cover of improved construction which may be utilized for not only transferring the details of `the sale upon the duplicate sheet and keeping a tally of the sales made but is of such a-construction that it may readily be detached from the book so as to serve for a number of books'and it consists essentially, first, of printing the numbcr of the duplicate sheet on the back thereof by reverse type yin, an ordinary web press and at the same time producing at the bottom end of each duplicate sheet a transparent strip so as to exhibit the number of the sheet in'proper` form through the strip, and, secondly, in making an indentationv in the top of the central portion of the cover, the

indentation being sufficiently wide so asto allow the sides of the inxlentation to pass on each side of the wire cleats or stitching and above the tongue which is connected by the wire cleats or stitchingJ to the stub of the book and furthermore in carbonizing one sheet of the cover and securing to the other sheet two or more tally sheets as hereinafter more particularly explained.

Figure 1, is a perspective View showing my book open ready for use with the ily leaf thrown down. Fig. 2, is a perspective View of the cover. Fig. 3, is an exaggerated longitudinal section through the book when closed. Fig. 4, is a perspective View of an alternative form of cover. Fig. 5, is an exaggerated longitudinal section through the book, flexible cover and sti cover.

'In the drawings like letters of reference indicate corresponding parts in each figure.

A, is the` body of the book, which is secured together at the cleats or stitching, o. l

c, is the duplicate leaf and, d, the fly leaf which normally liesupon the top of the duplicate leaf` as shown but is in the drawings thrown down so as to exhibit the transparent stub, a., by the wire stri-p, c', made across the bottom of the yduplicate leaf of suiicient width to allow the number vof the duplicate leaf to'be readily seen through the leaf.

' In printing'the'book the blanks in running through the press are numbered,the types being arranged and operated so as to print upon the back of the duplicate leaf the number of that leaf Vbackwardly but of course when viewed from the front of the duplicate leaf through the transparent strip the number will appear properly. In running the blanks through the machine the ltransparent strip or portion is formed across the blanks preferably by any mixture, as benziney and oil in suitable proportions, so as notv to materially disflgure or aect the handling of the duplicate sheet. Y

B, is the cover of the book, which is formed in three portions, e, f, and g. The cover is .formed of light Manila paper the portion, e,

.blank paper pads are held together.

f", is an indentation made in the top of the portion, f, of thecover, B.

h, 'is aitongue secured to the bottom of the book at the stub by the cleats, b, which pass through the stub as before described. The

cover is intended to be slipped up into posi= r tion between the tongue, h, and the bottom of the book, as shown in Fig. 3, the sides of the indentation, f', being designed to come on the outside of the cleats or stitching, b.

In Fig. 4, I showv the indentation made by simply cutting out the top portion, f', of the cover, B, and turning it down so as to form a tongue, f. When I place` my book in the stiff card board or outside cover, C, as indicated 1n Flg. 5, I insert the tongue, f, in the pocket, c, as well as the large tongue, h, so

, is a series of tally sheets attached. at

as to connect both the book and flexible cover to the stili outside cover.

Although I show the form shown in Figs. 4 and, 5, as an alternative form of making the 5 indentation still I prefer to make it in the form shown in Fig. 2. By making the indentation as shown it will be seen that the cover is detachably connected to the book so that it may be very quickly and readily rero moved from the particular book which it is being used for as soon as the book has been used up and may then be very readily slipped into position so as to form a cover for another book one of the tally sheets being also I5 readily detached from the top of the tally sheet so as to leave a blank tally sheet for recording the particulars of the sales in the next book. The tally sheet detached may be tiled away for record. It will also be seen 2o that the cover, B, may be utilized for several books and that by having the portion of the covercarbonized and margins left as shown the combined cover and carbon sheet may be very cheaply made.

It will be noticed in the cross sectional views that I show the leaves and other parts exaggerated in thickness in their diierences apart for the sake of clearness but it will of course be understood that all the leaves and 5o covers lie close together. It will also be un derstood that my carbon sheet or more properly called the carbonized portion of the cover will be manipulated so as to place it between the duplicate leaf` and iiy leafy by handling 3 5 the upper broad margime, without any danger whatsoever of soiling the lingers.

It will be seen that my cover can with equal facility be applied to what is known as the dat book that is to the book in which the duplicate leaf and the ily leaf lie flat in one 4o continuous leaf perforated at the stub and atthe point of junction of the duplicate leaf and ily leaf.

What I claim as my invention is- 1. In a duplicatingcheck bookand in com- 45 bination with the ily leaf, of the duplicate leaf having a transparent strip made across it in the paper itself above the reversely printed number on the back of the leaf as and for the purpose specified. 5o

2. In combination with the book A, the tongue h, secured to the upper end thereof and a cover B having itsunder section f provided with a cut out or indented upper end to clear the stitching which"`connects the book and tongue, the said section` f, adapted to be slipped in between the tongue and book A, substantially as described.

3. The combination with the duplicating check book ofthe portion, f, detachably con` nected thereto, the portion, e, partially carbonized and having margins, e', and, e", con; tiguous to the portion, f, at one side, and the portion, g, contiguous to the portion f, at the other side and provided with tally sheets, g', 65 having their edges connected together on the side, g, and portion of the side, g", as and for the purpose specified.
